AIR PURIFIER Filed June 9. 1927 Patented Oct. 14, 1930 UNITED STATES PATENT OFFICE NATHANIEL A. STRATTON, 0F BROOKLYN, NEW YORK, ASSIGNOR OF FORTY-NINE 0NE- HUNDREDTHS T0 PAUL A. BACHOR AIR PURIFIER application filed June 9, 1927. serial No. 197,601.

This invention relates generally to puritiers, and has more particular reference to an air purifier for attachment to the exhaust of gas engines.

The invention has for an object the provision of an air purier for association with the exhaust of gas engines, which is efficient and reliable in action.

The invention has for a further object the provision of an air 'purifier for the exhaust of gas engines, which is of simple durable construction, and which can be manuiiaetured and sold at a reasonable cost.

For further comprehension of the invention and of the objects and advantages thereof, reference will be had to' the following description and accompanying drawing, and to the appended claim in which the Avarious novel features of the invention are more par-v ticularly set forth.

Referring to the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a central vertical sectional view, certain parts not bein shown in section namely the discs, of a evice constructed acrording to this invention.

Fig. 2 is an enlarged fragmentary view thereof showing the disc in section, and the slanting wheels in place.

Fig. 3 is a vertical sectional view taken on the line 3--3 of Fig. 1.

Fig. 4 is a fragmentary face view of one of the discs from each ofthe nine different kinds of discs used inthe device.

T he reference numeral 10 indicates the surface of a support upon which a split casing 11 is mounted. Standard 12 from surface 1.0 engages shaft 13 of a gas engine not shown in the drawing. The shaft 13 is provided with a flywheel 14 which has an internal gear 15 secured to one side. A shaft 16 extends through casing 10, and one end projects therefrom, and a gear 17 1s secured to this end, and meshes with internal ear 15. The engine exhaust is connected gy pipe 18 to the upper part of the casmg, while water 19 iills the casing about one third full.

Nine rings 20, 21, 22, 23, 24, 25, 26, 27 and 28 are secured in the casing. Each of these rings has seven .spacer discs, and the spacer discs of ring 20 are numbered 29` of ring 2l numbered 30, of ring numbered 31, of ring 23 numbered 32, of ring 24 numbered 33, of ring 25 numbered 34. of ring 26 num bered 35, of rin'g. 27 numbered 36, and oi.' ring 28 numbered 37.

lfastened to the shaft 16 at thereto are whee each ring, that is, there are six wheels in ach ring. These Wheelsv are stamlied or are reticulated Wire screens so as to. have a pluraL ity of openings or pockets 38 secu in Fig. 2.

The spacer discs on the rings are formed with progressively decreasing apertures. as for example discs 29 have a )ertures 40 of a size 3/32 x 3/8"', discs 30 have apertures 41 of a size 1/16 x 1/4, discs 31 have apertures 42 of a size 1/32 X 1/8, discs 32 have apertures 43 of a size 1/64 x 1/16,` discs 33 have apertures 44 of a size 1/64" x 1/32", the-apertures 45 of discs 34 are TO mesh, apertures 46 of discs 35 are 80 mesh. apertures 47v of discs 36 are 90l mesh, and apertures` 48 of discs 37 are 10() mesh.

A suction fan 50 is secured to shaft 16 to force the gases from pipe 18 through the casing 11. The rear of the casi ng is provided with an cut-let 51, and the bottom with a water connection 52.

The operation of the device crmsists in the Wheels 38 rotating. as the flywheel 14 turns, and gases entering the casing 11 are forced to travel a great distance within the limited a slight angle area of the casing before they leave at the" exhaust end 51. They travel a greater distance since they whirl around the wheels which are turning at a high speed, say 1600 R. P. M. Attention is directed that the rings 20 to 28 luclusive. and the spacers or discs 29 to 37 inclusive remain stationary. Due to the progressively decreasing size of the apertures in the spacers the exhausting of the gases is retarded. The pocket-s 38a in the Wheels 38 are filled with the gases and deliver sarne against the water 19 which .act like hammer blows, and break up the gases, and eventually the water becomes completely saturated With carbon. The casing is then refilled with fresh Water. While the hammer 38, between the discs of blow operation is in progress, a denseness is created within the casing by the hot gases turning some of the water into steam which causes carbon deposits on the wheels and discs, which requires occasional cleaning so that the passages are not blocked. Due to the slanting mountings of wheels 38, they wobble, aiding in a better deliverance of the gases into the water.

While I have illustrated and described the preferred form, 'construction and arrangement of the several elements employed, it will be understood that the device is nevertheless susceptible of considerable modification therein, and I therefore reserve the right and privilege of resorting to all such changes as may be fairly embodied Within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

In an air purifier, a casing with a gas inlet at one end and an outlet at the other and partially filled with water, a plurality of transverse discs with Vperforations fixed within the casing, and a reticulated wire screen wheel between each two adjacent discs and arranged at a slant to the vertical and rotatively mounted for wobbling so as to slap gases passing thru the casing and momentarily caught in the reticulated wire screen against water partially filling the casing for the absorption of impurities from the gases into the water.

In testimony whereof I have afiiXed my signature.

NATHANIEL A. STRATTON.
